OpendTect is an open source seismic interpretation software system for processing, visualizing and interpreting multi-volume seismic data, and for fast-track development of innovative interpretationtools.

Optionally OpendTect can be extended with (closed source) commercial plugins.

The GPL license covers OpendTect. The software is released with its source code (C++), is not protected by a license manager, and can be used by anyone, including for commercial purposes, as long as the user accepts to adhere to the GNU/GPL rules.

2D, 3D, 4D & Prestack Seismic

Analyze 2D, 3D, 4D pre- and post-stack seismic data.

2D & 3D Viewers

Data processing and visualization are rigorously integrated in the OpendTect system. Visualization elements can be moved freely through data space to interactively analyze data from stored volumes, or data that are calculated on-the-fly.

Trace cross-equalization functionality that is used to correct small misalignments in 3D seismic volumes prior to further analysis. It is typically used to align time-lapse seismic data, multi-azimuth stacks or angle stacks (Residual NMO correction). Auto-loaded in OpendTect base.
